SHT Ultra Ceramic Zirconia Blocks Dental 900 MPa High Flexural
Strength
SHT Ultra zirconia ceramic blocks and ce zirconia blocks dental for
open zirconia blank and false zirconia blocks dental
Introduction of YUCERA's UT Multilayer high translucent dental
zirconia:
1. SHT multilayer zirconia blank is a dental multilayer zirconium
oxide (4Y-TZP cervical, 5Y-TZP incisal) with natural color and
translucency
gradient and high flexural strength(700 MPa ),
2. With as high as 49% translucent , monolithic restorations. The
soft material before sintering ensures an effortless manufacturing
process.
3. All-ceramic veneering is possible with the common all-ceramic
systems.
It impresses with its perfect balance between translucency and
strength for the production of aesthetic all-ceramic restorations.
The soft material before sintering ensures an effortless
manufacturing process.
Features of SHT Multilayer high translucent strong zirconium oxide
for fixed and implant-supported prosthetics:
1. Proven Aesthetics and used in CAD CAM digital system
2. Comprehensive color selection – 20 colors ( 16 A-D, 3 Bleach).
3. Maximum variety of indications – from the single-tooth
restoration to multi-unit bridge.
4. 900 MPa Bending Strength of zirconia disc.
5. 46% Translucency of zirconia disc.
6. High opacity – for discolored stumps.
7. High processing comfort – easy to mill.
8. Flexibility in processing – for fixed and implant-supported
prosthetics.
Indications
It suitable for Single-tooth restorations (anterior and posterior);
3-unit bridges (anterior and posterior) and Multi-unit bridges
(anterior and posterior).
Processing Options
1. Copings for full anatomical or partial veneering
2. Brush and / or dipping infiltration
